Figure l of the drawings represents a plan view of one of my improvedhawks inverted, and Fig. 2, a sectional view of the same on the planeindicated by line 2-2 in Fig. 1.

Referring by numerals to the drawings, 3 indicates the board of aplasterers hawk the same being solid throughout and as thin as possibleconsistent with the requisite strength to thereby lighten the tool. Theunderside of the board is fashioned to present a pair of parallel ridges4c at a predetermined distance apart, a center stud 5 and radial ridges6 that connect the ridges 4: with the stud. Matching the ridges andstuds of the board is a one piece metal frame comprising a pair ofparallel preferably angle-bars 7, a center plate 8 and radialbracestrips 9 connecting the plate and bars. The frame-bars arefastened, by screws 10, to the underside ridges 4 of the board, and thecenter plate 8 of the frame is provided with a center aperture for abolt 11, an angular inner enlargement of the aperture serving as arecess for the engagement of a nut 12 on the bolt.

The hawk-handle 18 is counterbored for the passage of the bolt 11through it and the plate and nut aforesaid, after which a plug 14- isset in said handle outward from the bolt-head. To separate the boardfrom the handle, said board and frame therewith are turned in the properdirection to run the nut 12 elf the bolt 11 this separation of saidSpecification of Letters Patent.
